Which term describes heat generation by rapid muscle contractions to raise temperature?

• A. Tremors
• B. Spasms
• C. Shivering
• D. Chills

Answer: (C)

Shivering is the body's way of generating heat through rapid, involuntary contractions of skeletal muscles. These quick muscle movements boost metabolic activity, releasing energy as heat to raise core temperature when exposed to cold. Tremors and spasms are general muscle activity patterns and aren’t specifically about warming the body, while chills describe the sensation of feeling cold (often with fever) rather than the mechanism of heat production. So the term that fits heat generation by rapid muscle contractions to raise temperature is shivering.
